Unpowered dive floating motion method and system applied to large depth submersible

Abstract

The invention belongs to the technical field of underwater motion control of deep water submersibles, and discloses an unpowered dive floating motion method and system applied to a large depth submersible. The method comprehensively uses a horizontal rudder, a vertical rudder, a dive ballast, a floating ballast, a vertical tilting adjustment system and the like, so that the submersible dives or floats at a certain pitch angle, so that the submersible is more streamlined in the moving direction during the dive or floating process, a water body is reduced in pressure when flowing through the outer surface of the submersible and presents a graded state, the sticking resistance is effectively reduced, and the total resistance is reduced. The method improves the speed of the dive and floating,so that the submersible has a longer underwater effective working time; the method is generally based on the basic components of the conventional submersible, improves the diving and floating speed ofthe submersible by means of function expansion, position adjustment, combined application and the like, reduces non-working time, and has a comprehensive advantage in terms of economy, operating habits and construction experience.

Description

technical field [0001] The invention belongs to the technical field of control of deep-water submersibles, and in particular relates to a method and system for unpowered submersible-floating movement applied to large-depth submersibles. In particular, it relates to a new unpowered submerging and rising-floating motion method applied to large-depth manned submersibles. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The area with an ocean depth of 6,500-11,000 meters is called the abyssal area, and the unique abyssal scientific issues such as ecology, biology, and geology in the abyssal area are the frontiers and hotspots of marine science. To study the abyss, it is first necessary to dive into the area with marine engineering equipment that can operate in the abyss area. Among them, the manned submersible is currently the most widely used in the world due to its strong operating capabilities and the ...

AI Technical Summary

Problems solved by technology

[0007] (1) The water resistance area of ​​the submersible in the direction of diving and rising is very large, and the speed of diving and rising is very slow;

[0008] (2) Increase the speed of movement by increasing the discardable load, increasing the negative buoyancy during the dive or increasing the positive buoyancy during the ascent process. Once the load dump system fails, the submersible will have a great safety hazard;

[0011] The difficulty lies in: how to speed up the speed of diving and rising is the difficulty solved by the existing technology;
